Preloading fonts for web performance with link rel=”preload”

from HTMHell [alt+shift+b] in programming

by Alistair Shepherd Web performance is incredibly important. If you were here for the advent calendar last year you may have already read many of my thoughts on the subject. If not, read Getting started with Web Performance when you’re done here! This year I’m back for more web performance, this time focusing on my favourite HTML snippet for improving the loading performance of web fonts using preloads. This short HTML snippet added to the head of your page, can make a substantial improvement to both perceived and measured performance. <link rel="preload" href="/nova-sans.woff2" as="font" type="font/woff2" crossorigin="anonymous" > Above we have a link element that instructs the browser to preload the /nova-sans.woff2 font. By preloading your critical above-the-fold font we can make a huge impact by reducing potential flashes of unstyled or invisible text and layout shifts caused by font loading, like here in the following video: Recording of a page load illustrating how a font loading late can result in a jarring layout shift How web fonts are loaded To explain how preloading fonts can make such an impact, let’s go through the process of how web fonts are loaded. Font files are downloaded later than you may think, due to a combination of network requests and conservative browser behaviour. In a standard web page, there will be the main HTML document which will include a CSS file using a link element in the head. If you’re using self-hosted custom fonts you’ll have a @font-face rule within your CSS that specifies the font name, the src, and possibly some other font-related properties. In other CSS rules you specify a font-family so elements use your custom font. Once our browser encounters our page it: Starts streaming the HTML document, parsing it as it goes Encounters the link element pointing to our CSS file Starts downloading that CSS file, blocking the render of the page until it’s complete Parses and applies the contents of that file Finds the...

#35 a perfectly structured button

button table { margin: 0; } .fa-arrow-left::before {content:"←"} Bad code <button type="button" onclick="window.open('https://example.com/other-page')"> <table> <tbody> <tr> <td> <i class="fa fa-arrow-left" aria-hidden="true"></i> </td> <td align="left">Back</td> </tr> </tbody> </table> </button> Back Issues and how to fix them The HTML isn't valid because the table element isn't allowed as a child of the button element. Based on the content categories listed on MDN, the table element qualifies as flow content and can only be placed inside an element that expects flow content. The button element, on the other hand, expects phrasing content, not flow content. The semantic information of the table doesn't cause any issues because the button's content is presentational See Buttons Role on W3C, Presentational Children. Keep it simple and structure the button element using CSS, such as Flexbox. Instead of using tables to structure the button element, use phrasing content elements, such as span, img, or SVG.

A link on a logo in the header, what should the alt-text be?

by Rian Rietveld It's a common pattern to use a logo in the header as a link to the homepage. Fun fact: the alt text of the image inside a link, will be added to the link text. The problem with linking a logo is that it serves 2 purposes: a logo, that tells you which site you are visiting; a link, that leads to the homepage. So add both that info in the alt text. Explain what's on the image and where the link leads to: "Site name logo, to the homepage". Note: Start the alt text with the visible text, then the link will be easier to target for people using voice recognition software. Let's take as example the logo of my home town Leidschendam-Voorburg. In code (simplified): <a href="/"> <img alt="Leidschendam-Voorburg logo, to the homepage" src="logo-lv.svg" /> </a> Generated HTML: VoiceOver in Safari will announce this as: All info is there. There is an advantage of using the alt text instead of an aria-label solution. When the connection is slow, the alt text will show up before the image does and already informs all users of the site name and link destination. It's quite robust. Discussion Do I need the word logo? Isn't that redundant, like the word image or picture? Yes, in this case the fact that this is a logo tells important info. Not only for blind users, but for all screenreader users. If you are visually impaired but not totally blind, you may see the image vaguely. With the addition of the word logo, you also know what the image is. The site name is required, but the logo gives extra context. Isn't this a violation of 2.5.3 Label in Name? No, the visible name is in the alt text, which becomes the accessible name of the link. Adding extra context to the link is common practice. Compare this with the notorious "Read more" link in a card. A common pattern is to use a sr-only CSS class (or equivalent) with additional text: <a href="url">Read more<span class="sr-only"> about cute kitten</span></a> . You see Read more. You hear Read more about cute kitten. In our case: You see the site name and logo; the visual position tells the link destination. You hear the site name, the fact it's a logo and the link destination. The whole visible text should be in the accessible name, but extra information, like the meaning of the image and link destination can be added for context. That way the purpose of the link is explained. Why didn't you use an aria-label? Of course there are other and also valid solutions. By using plain simple HTML I want to honor the first rule of ARIA: If you can use a native HTML element or attribute with the semantics and behavior you require already built in, instead of re-purposing an element and adding an ARIA role, state or property to make it accessible, then do so. Happy Holidays!

#34 a button is not a link

Bad code <button type="button" onclick="window.open('https://example.com/other-page')">Link target description</button> Issues and how to fix them A button opening a link will be unexpected behavior for screen reader users. No matter how it is styled. Links disguised as buttons won’t show up in the link list of a site in assistive technologies. Use links for navigation to other pages or sections, and buttons for actions performed on the current page or within the application.

#33 make me one (input) with everything

The good intentions were there but in the HTML and Accessibility world, less is sometimes more. Bad code <label for="textinput">First name</label> <input type="text" id="textinput" aria-label="First name" placeholder="First name" title="First name"> Issues and how to fix them The aria-label, placeholder, and title attributes all provide the same informaton ("First name"), leading to the screenreader reading the same text multiple times. The aria-label is unnecessary since the input is already correctly labeled by the <label> element. <label> elements should be preferred to aria-label since they are also visible to sighted users. The title attribute is not needed here, as the label and placeholder already convey the necessary information. Using title in this context adds unnecessary complexity. The placeholder text should provide a hint / example to the user what kind of input is expected, it should not act as a label or contain the same content. Good code <label for="textinput">First name</label> <input type="text" id="textinput"> Resources <label> on MDN aria-label on MDN placeholder on MDN title on MDN

The UX of HTML

by Vasilis van Gemert Recently when I gave a coding assignment — an art directed web page about a font — a student asked: does it have to be semantic and shit? The whole class looked up, curious about the answer — please let it be no! I answered that no, it doesn’t have to be semantic and shit, but it does have to be well designed and the user experience should be well considered. Relieved, all of my students agreed. They do care about a good user experience. The joke here is, of course, that a well considered user experience starts with well considered HTML. Somehow my students are allergic to semantics and shit. And they’re not alone. If you look at 99% of all websites in the wild, everybody who worked on them seems to be allergic to semantics and shit. On most websites heading levels are just random numbers, loosely based on font-size. Form fields have no labels. Links and buttons are divs. It’s really pretty bad. So it’s not just my students, the whole industry doesn’t understand semantics and shit. Recently I decided to stop using the word semantics. Instead I talk about the UX of HTML. And all of a sudden my students are not allergic to HTML anymore but really interested. Instead of explaining the meaning of a certain element, I show them what it does. So we look at what happens when you add a label to an input: The input and the label now form a pair. You can now click on the label to interact with a checkbox. The label will be read out loud when you focus on an input with a screenreader. When you hover over a label, the hover state of the connected input is shown. My students love stuff like that. They care about UX. I show them that a span with an onclick-event might seem to be behaving like a link, but that there are many layers of UX missing when you look a bit closer: right-click on this span, and a generic context menu opens up. When on the other hand you right-click on a proper link like this one a specialised context menu opens, with all kinds of options that are specific to a link. And I show them that proper links show up when you ask your screen reader to list all the links on a page, yet spans with an onclick-event don’t. Moreover, a span doesn’t receive focus when you tab to it. And so on. My students see this and they get it. And they love the fact that by being lazy they get much more result. So when I teach about HTML I always start with the elements that are obviously interactive. I show them the multitude of UX layers of a link, I show them the layers and layers of UX that are added to a well considered form. I show them what happens on a phone when you use an input with a default text type instead of the proper type of email. They get this, and they want to know more. So I show them more. I show them the required attribute which makes it possible to validate not only form fields, but also fieldsets and forms. They love this stuff. Then I go on and show the details element with a summary. Whoah! No JavaScript! These interactive things are the most important parts of HTML. These are the things that truly break or make a site. If you don’t use these elements properly, many people are actively excluded and the UX degrades in many ways. The interactive elements are what makes the web the web. The old focus on semantics Every time I come home from a web conference I hang the lanyard with the badge on a doorknob. There are at least 35 lanyards there. The oldest is more than fifteen years old, the newest just a few months. On most of these conferences there was someone telling us about the importance of using proper semantic HTML. And they all talked about the importance of heading levels. So for at least 15 years we’ve been telling the web design and web development community that heading levels are very important. Yet after all these years, and after all these conferences there are almost no websites that do it right. Later, when HTML5 was introduced the talks about semantics were still mostly about creating a proper document outline, but this time with sectioning elements in combination with headings. Unfortunately this idea was never properly implemented by browsers. And it turned out that these sectioning elements are very hard to understand. For years I’ve tried to explain the difference between a section and an article, and almost nobody gets it. And of course they don’t, because it’s very, very complicated theory. And above all: There’s no clear UX feature to point at. The user experience doesn’t change dramatically if you use a section instead of an article. It’s mostly theoretical. So nowadays, next to divitis, we also have sectionitis. Understanding how heading levels work is hard. And understanding how sectioning elements work is really hard. And explaining these things is even harder. What’s the use for theoretical purity if the end result is the same? Yes, I know that some sectioning elements actually have some UX attached to it. But not that much UX if you compare it to the real interactive elements. Not getting your heading levels right is not at all as destructive as using divs instead of links. Now, I’m not saying that we should stop teaching people about heading levels and sections. We shouldn’t. Heading levels and sections do things as well. But we should think about when we teach these more complicated and subtle parts of HTML. First we need to get people exited about HTML by showing all the free yet complex layers of UX you get when you use the interactive elements properly. And then, when they do understand the interactive elements, when they’re really excited and they ask for more, show them the more obscure UX patterns. You need a good idea of what UX is before you can understand things like the option to nagivate through the headings on the page with a screen reader. Without an idea of what UX means you cannot understand what landmarks do. First start with the obvious, then show the details. I am very much looking forward to 15 more years of web conferences and publications. I look forward to seeing inspiring talks about the UX of HTML. Talks about the incredible radio button and its wonderful indeterminate state! Talks about validating forms in a friendly way with just HTML and some clever CSS. Talks about the different context menus that appear on different elements. In other words, talks about what HTML does, and much less about what it means in theory. Let’s talk about user experience, and let’s stop talking about semantics and shit.

Haunt 0.4.0 released

I'm quite a bit late on this one, but Haunt version 0.4.0 was released released back in July. I haven't had much time for blogging, but I'm catching up now! This release contains a small set of improvements and bug fixes since the 0.3.0 release in 2024. About Haunt Haunt is a static site generator that uses the Guile Scheme as its configuration language. It aims to be simple, functional, and extensible. Features include: Easy blog and Atom/RSS feed generation Markdown post support Simple development server for viewing edits before publishing Purely functional build process User extensibility Notable changes Added support for HTML in Markdown documents. This was a long time coming because guile-markdown did not support it and the library was abandoned by the original maintainer. As part of my work at Spritely, we forked it, implemented the relevant portions of the CommonMark specification, and released it. Spritely's guile-commonmark fork is now considered to be the official upstream by Guix and others. A further consequence of this is that guile-lib is now a required dependency for building Haunt as we need the (htmlprag) module to parse Markdown documents with embedded HTML. html->shtml from guile-lib's (htmlprag) module is now used instead of xml->sxml in the HTML reader. It was silly of me to use xml->sxml for this purpose years ago, but at the time I wanted guile-lib to be an optional dependency. Added haunt new subcommand for creating a new site. Added default directory, template, and prefix arguments to flat-pages procedure. Added support for index metadata flag to flat pages for pretty URLs. Flat pages now receive all page metadata, not just the page title. This is a breaking change from 0.3.0. Added .scm as an additional extension for sxml-reader. make-file-extension-matcher now supports multiple extensions. Fixed emission of <script> and <style> elements. Fixed handling of no available reader in flat pages builder. Fixed unreachable error handling clause when a reader is not found for a post. Fixed default blog theme template missing an <html> tag. Fixed overloaded -h option in haunt serve. Deprecated post in Skribe reader in favor of document. Download Haunt 0.4.0 is already available in Guix: guix pull guix install haunt See the Haunt project page for information on how to build from source. Thank you to Camilo Rodrigues, Noé Lopez, jgart, Jakob L. Kreuze, and Daniel Meißner for their contributions to this release! Happy haunting!

I Bought A Scanner (No, Really This Time)

This is a transcript from a talk I gave at the German Perl Workshop earlier this year. If you'd prefer to watch the video recording, you can find it here. I have lots of photographic projects on the go. Lots of these being on film, as some of these I started shooting a long time ago. I don’t have any particular loyalty or attraction to film, it’s just that I started shooting many of these projects before affordable medium format digital was available. Since I mostly shoot medium/large format film I never really jumped to digital until recently, so film has continued to feature heavily in my workflow. That said, it’s a pain in the arse to shoot film now given the spiraling costs, limited availability, and issues around traveling with it: modern airport CT scanners, being rolled out across many airports, are much more convenient but will fog film. Asking for a hand inspection often comes down to arbitrary timing - how busy the security is, how experienced the operator is, or if you’re lucky/unlucky. I’ve had film forced to be scanned (and fogged) and politely argued with security on more than one occasion. I don’t want to deal with that so don’t travel with film anymore, thus I am shooting less of it and have mostly moved to digital. I still have a tonne of film I need to scan and process however. Here’s just some of the binders and files of film. I don’t plan to scan all of this, but I do plan to scan the ones I need to. Probably in the region of a couple of thousand frames. I want to scan to the highest possible quality (within reason) for archiving, book projects, and large prints. If you’re wondering how large I print, it can be up to 160x60cm panoramics for selling. This is restricted by the size of my printer (that’s another story). Three Years Ago Three years ago I almost bought a scanner. I ended up blogging about it and the post got a bit of traction on Hacker News (HN). I’m never quite sure which posts I submit will pique the interest of the users. I’ll spend months chipping away at a draft and when I post it it tanks. Or I’ll cobble something together in twenty minutes, like the linked one above, and it gets 440 points and over 300 comments… The thread had some useful suggestions and some not so useful ones, the not so useful ones being effectively “buy an Epson”: I’ve had one for fifteen years and it’s not good enough for large prints or archiving. It’s passable for web stuff and smaller prints, but for my recent use cases? Not even close. Ten years ago I had negatives scanned with a high resolution scanner for the first time and recently, wanting to scan my archives for various projects, I decided I should invest in one of those scanners. The Original Plan The plan, back in 2023, was simple: Buy scanner (at significantly reduced rate) Scan all my film Sell scanner Profit! And I mean profit - the scanner that I almost bought was being offered to me at about 2/3rd of the price they usually sell. And they’re becoming harder to find in working order so the prices are going up. Or profit in not having to pay > 25.- CHF per frame to have someone else do this. You can see the pricing from The Film Lab. You can read the original blog post to find out more about the scanner in question, so I won’t repeat it here. Other than the parts being relevant to the rest of this post, namely that the scanner was showing hard and soft problems. The software that drives the scanner was last updated in 2012, it’s proprietary and closed source, requiring 32bit architecture and no third party drivers or software exist. So you are stuck using old software/computers to run it. Or maybe you could use emulation / virtualisation? The problem there is that the interface is firewire, or SCSI on the even older models, and firewire is known to be problematic on these scanners as the controllers start to go bad after a decade of continued use. That’s a risk, and the scanner was very much EOL as the firewire controller was dying: both ports were bad that suggests controller, not ports. The scanner would have been €5,000 to purchase and then €3,000 (ish) to repair. Or, as HN suggested - just open it up and use a soldering iron. I’m not going to drop 5k on something and then start poking it with a soldering iron. I’ll pass on that thanks. Camera Scanning In the meantime I’ve been camera scanning, which you can read about in another blog post. But how does that compare cost wise? It’s expensive because you’ll need a high resolution camera, a macro lens, copy stand, negative carrier/holder, and quality light source. You’ll look to spend anything from three to five thousand Euros on everything. Camera scanning does actually work well, in that it’s close to a high resolution dedicated scanner. But you have to setup the entire thing every time you want to use it, including ensuring everything is straight and parallel. It also suffers from the same weakness as most other scanning methods. What do you think that is? Film Flatness Or lack thereof: Film is rarely flat, especially so with 35mm. These are pretty mild examples of curl. It tends to be flatter in the larger formats but then you get into flatness issues due to it sagging. The smallest difference in the film plane can cause major issues in sharpness due to focus fall off (film scanning is essentially macro photography). Any workflow or solution that does not take this into account is significantly compromised. And the workflow is only as good as its weakest part. This is the biggest problem in scanning film - all other considerations are more than adequate these days: resolution, dynamic range, etc. However, most negative carriers don’t keep the film perfectly flat. This has always been a problem - this is from a book called “Edge of Darkness” which is about traditional analog photography and printing, and summarises the problems of negative carriers thusly: “if you use a glassless negative carrier, you might as well just buy the cheapest enlarging lens you can find. You are simply throwing away the money and sharpness you paid for it in your enlarging lens, and also in your fine camera and the expensive lenses you bought for it… No film will lie flat in a glassless carrier. That’s right, none… There is no avoiding this issue. Use glass.” So you have to use (anti-newton ring) glass, which introduces other issues - you’ve now got extra glass in the transmission path, and dust (which isn’t a massive problem, but a pain nonetheless). You could use drum scanning, which is absurdly impractical from a cost and operating point of view. Or you could use a Flextight, the scanner I almost bought three years ago. Interim Solution I stuck with camera scanning, but wasn’t happy though, because of film flatness and the setup faff. So of course I started looking for another scanner. I was idly browsing near the end of 2025 and came across this one. It’s exactly the same spec as the one I tried three years ago, except SCSI not Firewire so less prone to failure. It just predates Hasselblad buying Imacon (so is pre the rebranding, etc). It was in Switzerland so I could inspect and pick it up. It was also significantly cheaper than the previous one I had looked at, so worth a punt even if I needed to take a soldering iron to it. We went to St Gallen for a weekend and I picked it up. Here’s the software interface back in my studio. Look at that marvelous interface! None of that liquid glass bollocks. The first scans were promising, but I had the sense things needed some TLC. The first thing was calibrating the focus, which the software can do in combination with a focus slide. I was lucky that the focus slide was included with the scanner and I’m not sure what I would have done otherwise. Probably paid a fortune for a replacement? Possibly a lot of manual trial and error with the software? After doing that I scanned images of the 1951 USAF resolution test chart (taken on ultra high resolution 35mm film): That’s what the resulting scan looked like. Notice that it’s sharp from edge to edge, corner to corner. At 100% crop we can resolve around 110 to 123 line pairs per mm, which equates to about 5,600 to 6,300 DPI. This is beyond the limit of most 35mm lenses, but importantly - exactly to spec for this scanner. So I was happy the focus was calibrated. If you’re curious this is the same target with the camera scanning setup. It’s close, but we’ve got another variable in the workflow, several even, and that impacts the results. It’s not as sharp, and the extra glass in the transmission path causes aberrations. Another thing that needed attention was the power supply. The seller mentioned that “sometimes it takes five minutes to warm up”. Sometimes it was more than five minutes, and the power supply would click click click away. So that needed fixing and it was easy enough to find a compatible new replacement, however it cost 200 Euros. Expensive! The third problem I noticed was that some of the scans were coming out stretched. Often about 10% too wide/long, sometimes more than that. My panoramics looked panoooooooramic. I did some research and someone suggested this might be a “buffering issue”, which I thought was nonsense. Doing some testing I heard slipping sounds when the scanner was pulling the film into the body. After more research I stumbled on a post that suggested the belts need replacing. I opened the scanner up, and sure enough: A ha! You can’t quite see that the one on the back is even worse. I replaced those with compatible belts: 535 synchroflex t 2.5/245. Problem solved. The fourth problem was that the film holders were old and/or had been mishandled. They were falling apart and held together with electrical tape or glue, which didn’t seem optimal. Replacements cost 350 Euros in total for the four I needed. They’re now available cheaper from China, since the patents have expired. Or, you know, China. They used to cost about 200 Euros each from Hasselblad. The fifth problem, which is a potential one and hasn’t manifested yet, is that the lamps may eventually need replacing. I picked up a couple for 25 Euros. That seemed like a reasonable thing to do while they’re still available. Success? Let’s add up the costs of acquiring this scanner and renovating it: Scanner: 1,750.- CHF Power Supply: 175.- CHF Belts: 25.- CHF Film Holders: 350.- CHF Lamps: 25.- CHF Total: 2,325.- CHF (c. 2,500 EUR) In the last year (since acquiring the scanner) I have scanned: c. 250 panoramics frames (~ 6,000 CHF) c. 2,500 medium format frames (~ 80,000 CHF) c. 200 large format frames (~ 9,000 CHF) The figures in parentheses are what it would have cost me to have that number of frames scanned by a third party. That is, er, quite a saving. Also quite a lucrative business model perhaps? I think I can argue the cost of the scanner was a very good investment, and I haven’t finished using it yet. Even if it were to stop working tomorrow, it has already paid for itself many times over. Could it stop working tomorrow? Yes, because of other issues that will be harder to solve. The Bigger Issue(s)? A Power Mac G4 (discontinued in 2004). This came with the scanner, the necessary hardware and software to drive it, and is almost certainly living on borrowed time. Spinning metal is never good in the long-term. I’ll maybe purchase a backup soon, as these can still be found for a couple of hundred Euros. The key thing though, is that this very expensive, very high quality scanner, will at some point be rendered useless by the upgrade treadmill because the software required to run it will be increasingly difficult to run. A scanner that is still used by businesses, educational institutions, and individuals like me. A scanner that originally cost tens of thousands of Euros less than a decade ago. The upgrade treadmill is constantly whirring away. This is from the top of the Seattle Space Needle. “Do not upgrade anything on computer”. Clearly that notice speaks of someone being bitten by an upgrade at some point. I wonder is anyone else feeling the fatigue? Security updates, sure I can understand. But feature creep and trivialities? No! What tangible benefits have the last ten, fifteen, or even twenty years of OS updates brought? Other than security, and compatibility with newer hardware? New hardware is great, really, but by association forced deprecation of older hardware. No! It feels like the upgrade treadmill gets faster and steeper every year. Add to that subscription lock-in and dead endpoints: “I couldn’t vacuum my house because an SSL cert had expired” is what someone told me earlier this year. Fortunately this person is a software engineer so ended up man-in-the-middling the network traffic to get the vacuum cleaner to work again (no SSL-pinning it seems). “GoPro is announcing the end of life of the GoPro Quik app for macOS, effective at the end of 2024”. They discontinued the former in favour of their mobile app, which requires an account, login, subscription, and so on. I just want to transfer the videos from the hardware, I don’t need any of this crap (I don’t need any of that crap, it turns out GoPro haven’t locked the device down enough to prevent using third party apps to access the files. Yet). And, of course, software has to be in everything. These days the scanner would/could have an embedded Raspberry PI? Just a keyboard and mouse input, monitor and USB output would reduce the surface area, connectivity issues, and software dependency. Or software is never done? Because: externalities. I guess software is “done” when it’s no longer supported? Marciano Planque has a good piece on this: When hardware products reach end-of-life (EOL), companies should be forced to open-source the software. I think that’s a fair thing to say. I suspect Hasselblad/Imacon never open-sourced the software due to licensing issues. Or they just lost the source. Or they just don’t care, I don’t know. Maybe some combination of the three. And, inevitably, discontinued hardware like this scanner. Or, that is to say, discontinued parts? What about regulation changes? The panoramics I shoot are with a camera that was discontinued in 2004 because EU regulation banned lead solder in circuit boards. The company decided redesigning the parts wasn’t worth it. Old hardware has new exciting ways to fail. As time goes on components will fail or loosen - components that were expected to last decades. Then that results in tribal knowledge, or worse link rot and QR code rot. A lot of this stuff is hidden in walled gardens. There’s a Facebook Imacon group, for example. Why in the ever-loving fuck is a group for technical people, by technical people, on Facebook? Then there’s misleading AI. “My flextight scans are coming out stretched, what might the problem be?” LLM’s have gobbled up all the right information, and all the wrong information. Or information that is massively out of date. Nowhere in the suggestions here does it mention the belts might need replacing, which, according to my own research, is the most common reason these days. Legacy Software A decade ago I wrote an essay that also hit the front page of HN: All Software is Legacy. I think it is still relevant today, some parts not so much given we are now in The Age of Prompt, but mostly it’s still true. Nicholas always said “legacy software is the ugly stuff that makes you money”, which I think is true. But now it’s the stuff that surrounds us, like when I want to withdraw cash (guess what software most cash machines are still running?). Or when I want to take a train - when I gave this talk in Germany I had to get from the airport to the city centre. The ticket machines were disabled with a sign saying “no longer in use, download the app”. Then register. Then buy the ticket. I just want to give you money. Or when I wanted to pay for parking while stopping off at some random town in the UK - the same situation as with the ticket machines. “Download the app, register, pay”. Fuck that, I went and parked somewhere else. I just want to park, I don’t want to fight with software. Or if I want to hire a bike (not pictured: the half dozen apps on my phone to hire a bike). And when I want to buy stuff from a shop… One of the self-checkouts crashed recently in the coop, rebooting into a version of SUSE Linux from well over a decade ago. We’re collectively creating more and more of this everyday, letting it out into the world where it becomes a future liability for someone or the death knell for something. A pile of bikes, an unplugged ticket machine, a top of the line but no longer driveable scanner.

Attention is all you have

The Tetris effect is one of psychology’s most easy to reproduce experiments. Simply spend a bit of time playing the eponymous game every day for a few weeks. After a little while, you’ll start recognizing familiar Tetromino shapes in clouds, buildings, and everyday objects. You might even see them appear before your eyes when you start falling asleep. Tom Tang Attention hijacking There’s one lesson the Tetris effect teaches us: whatever you focus on long enough will end up shaping your thoughts. This can be a good thing since it’s how we learn new skills and discover new ideas. Sadly, less and less of our attention is focused intentionally. Instead of picking what we want to see we let other people decide what is supposed to be good for us. Do you want to watch a video? YouTube knows you like cooking and art streams. But why not also recommend a few clips about the stock market bubble, global warming, and the war in Iran. Doomscrolling will make you stay longer and click on a few more ads. Do you want to listen to music? Just open a Spotify playlist and let the algorithm figure out what you like. Please ignore the AI slop they will insert in between real songs to avoid paying royalties to real artists. Do you want to know how your colleagues are doing? Too bad, LinkedIn will bury any relevant career news between the opinion of complete strangers. It is surely just a coincidence that those strangers happen to be shilling whatever Microsoft is invested in at the moment. Do you want the opinion of strangers on a product? Well those Redditors you wanted to ask are probably just a bunch of LLMs talking to a bunch of Russian trolls now. I hope you didn’t value their opinion too much. If, like me and most people, you spend the major part of your day focused on your device, there’s no doubt it’s affecting you. And when you let someone else dictate what appears on your screen, it’s the same as giving them the key to your brain. New York Said Back to an intentional internet The internet wasn’t always like that. Before recommendation algorithms where a thing, you had to decide what you would be doing on the computer. You didn’t really have one big app that you could open and order it to entertain you. Instead, you had a few dozen of bookmarks to websites, each with a specific idea in mind. A site for video game news, that one website with lots of tutorials, a blog about anime that didn’t update often enough, a wiki about a TV show from the 90s… Of course awful things existed on the web. We had Encyclopedia Dramatica and Rotten.com, but you actually had to put the effort to go there if you wanted. Nobody was going to put pictures of dead kids and far-right propaganda as a suggestion after a pancake recipe or a cat video. The good thing is that this intentional internet is still around. It has just been a bit buried below the corporate web, but it’s not very hard to find. After all you’re on this blog, so you probably already have a good idea about it. The main difference between this time and now is you. When you want to get back to reading blogs, RSS feeds, and finish that tutorial instead of doomscrolling shorts, you have to get used to a slower internet. One where content is not infinite and doesn’t get updated every click. But like every habit, the only thing you have to do is to keep at it. And if you pay enough attention to it, something will click in your brain.
